Own cloud server app on Thecus

I have a Thecus N5550 storage unit and I have the Thecus server application installed. I have been using the Thecus client without issue until recently when I updated the client. Now, the client tells me the server side version of OwnCloud is out of date, use at my own risk.

My question is: Is there an effort to update the application/plugin for the Thecus to match the client software?

The server side is:
The version of the Mac client is: 2.2.3


you won't find the people which have build that app in here (it was not built by anyone related to ownCloud or owncloud.org). Maybe try to ask at a community dedicated to that NAS system.
